Order of operations.  We would have to move it to after <configs/...h> 
(and change behavior, and break a few board files, git grep 
CONFIG_BOOTM_ include/) or make everyone not using the standard undef to 
get their table, which I started down (as you could see from the patch) 
but it's quite invasive.  Or we add a fallbacks file and have config.h be:
First: default commands <config_cmd_default.h>
Second: Global defaults <config_defaults.h>
Third: board <configs/...h>
Fourth: arch fallbacks <asm/config.h>
Fifth: Global fallbacks

Since developers should be tweaking just their board config file I'm 
calling what's before defaults and what's after fallbacks..
